JOIN US AT THE RTA IN PORT ELIZABETH ON SATURDAY 4 JUNE

You are listening to ZS6SRL. Stay tuned for more details on these and
other important and interesting news items.

158 CANDIDATES TO WRITE RAE THIS WEEK

158 Candidates will write the Radio Amateur Examination on Thursday
this week at 16 venues across the country. The SARL wishes all
candidates the best of luck for the examination and would like to thank
all of the clubs that have been involved with the teaching and guiding
the candidates.

The examination starts at 19:00 and continues until 22:00. Candidates
are urged to arrive at the examination venue before the starting time
and present their ID documentation and exam number. The exam number can
be found on www.sarl.org.za. Candidates without an ID will not be
allowed to write the exam.

The examiner and moderator's advice to candidates is "read the question
several times before answering. There is plenty of time to complete all
the questions."

NEW 40 m BEACON TO TEST NAVIS CONDITIONS

On 7 May 2011 a new beacon was switched on in Bloemfontein to test
NAVIS conditions from the central Freestate. The beacon operates on 7
027 kHz running 50 mW into a dipole antenna 6 metre above the ground.

The purpose of the new beacon is to test propagation conditions from
central South Africa. The antenna in use is set up for NVIS conditions.
NAVIS is the acronym for Near Vertical Incidence Skywave. It is a
radio-wave propagation method that provides usable signals in the range
between ground wave and sky wave distances, usually between 50 to 650
km. The radio waves travel upwards into the ionosphere, where they are
refracted back down and can be received within a circular region up to
650 km from the transmitter. If the frequency is too high, refraction
fails to occur and if it is too low absorption reduces the signal
strength. The usable frequencies for NVIS communications are between
1,8 and 15 MHz.

The beacon sends the following message in an endless loop in CW at 5
words per minute: "VVV DE ZS4BOT/B KG30BV." The beacon's position is
KG30BV. The beacon and software was designed and built by Jan, ZS4JAN.
Reports can be sent to .

ARRISAT TO BE LAUNCHED LATE JULY

The cosmonauts on the International Space Station reported that they
activated the satellite and confirmed that they heard the signal on the
amateur radio equipment on board the ISS. Since the battery was nearly
depleted of its original charge, they switched the satellite off after
six hours of operation in order to prevent over-discharging the
battery. The battery was then removed from the satellite and stored
separately as per their normal battery handling procedures.

RSC-Energia reported that their plan is to recharge the battery about
three weeks prior to the EVA deployment. This will give the cosmonauts
time to reinstall the battery and test the satellite to make sure it is
working properly. The EVA deployment is planned for late July of this
year.

Find out more about ARRISAT and how you can enrich the lives of young
people at the SA AMSAT Space Symposium next Saturday 21 May. Get
details and the registration form on www.amsatsa.org.za.

PROPAGATION REPORT

Hannes Coetzee, ZS6BZP, reports that the solar activity is at low
levels. There is currently no chance for strong solar flares. Currently
sunspots 1 208 and 1 210 are the only real visible sunspots on the
earth facing side of the sun. A small sunspot is trying to form towards
the southwest portion of the visible solar disk. For the people doing
their own frequency predictions the expected effective sunspot number
for the week is about 35.

15 m will provide the best opportunities for DX followed by 20 m.
